Active colloids are colloidal systems able to consume energy to produce work, such as directed motion. Self-propulsion in micrometric particles can be achieved through surface asymmetries, using diffusiophoresis (via asymmetric catalytic properties) or thermophoresis (via asymmetric light absorption). However, the combining of several active properties into one single colloidal system remains poorly explored. In this work, we present a hybrid system synthesized by combining distinct nanoparticles, and investigate its ability to exhibit diffusiophoresis, thermophoresis, and respond to magnetic field gradients.
